Put the inputs in the boxes and choose the operation.  Use PI and NE instead of π and e (Euler's number).  Use A or B or C if you want to use previous output as input.  Use M if you want to use data that you have written or copied in the M box.

=   A

=   B
[ For (-32)^(1/5) compute 32^0.2 and operate ±:  (-32)^0.2 would signal "error". Note that (-32)^(1/n) with n even is not defined instead ]

Enter the data separated by commas  (each possibly followed by *... with ... its frequency)

=   C
